PostgreSQL version: 8.1.0
Operating system: AIX 5.3
Description: AIX: libraries contain the symbol main
Details:

Problem:
with xlc compiler under AIX 5.3 (also 4.3) we found the following problem.
The linker per default assumes that
you are linking a main program when you do not specify a module type. So
shared libraries contain the symbol
main. So you couldn't use the libraries

Solution:
Using LDFLAGS_SL="-bnoentry"
=> noentry point is specified.
=> no symbol main

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match

How did you configure postgres? Every AIX build that I have seen
includes "-Wl,-bnoentry" as part of the LDFLAGS_SL, which is sourced
from src/makefiles/Makefile.aix (I know that a non-gcc build on aix3.2.5
would use "-e _nostart" instead).
